"Twelve more than the product of six and a number is thirty" can be turned into this equation: 6x + 12 = 30.
In this equation, we solve for x.
Since the equation equals 30, we can subtract 12 from 30, which is 18.
Now, we know what 6x equals, which is 18.
6 x 3 equals 18, so x = 3.
Hope this helps! :)
